<h1 class="topictitle1">使用Hot-Add传输模式备份虚拟机时，备份任务一直重试</h1>
<div><div class="section"><h4 class="sectiontitle">现象描述</h4><p>使用Hot-Add传输模式备份虚拟机时，备份任务详情重复显示<span class="uicontrol">“节点XX准备备份任务”</span>，客户端日志中重复打印“==================stack list==================”堆栈日志，vCenter Server界面可查看到客户端所在虚拟机存在残留磁盘。</p>
</div>
<div class="section"><h4 class="sectiontitle">可能原因</h4><p>虚拟机前一次备份或恢复任务未正常结束，导致客户端所在虚拟机上的磁盘残留异常。再次进行备份时，VDDK无法正常自动清理残留磁盘，导致备份任务一直重试。</p>
</div>
<div class="section"><h4 class="sectiontitle">处理步骤</h4><ol><li><span>终止正在重试的备份任务，确认客户端所在虚拟机不存在其他执行中的任务。</span></li><li id="vmware_gud_0149__li17403167133818"><span>使用浏览器，登录vCenter Server。</span><p><p id="vmware_gud_0149__p3458193034817">登录地址：<strong id="vmware_gud_0149__b1245883004818">https://</strong><em id="vmware_gud_0149__i44581430154817">vcenter_server_ip_address</em></p>
</p></li><li><span>在左侧导航树上选择对应的客户端所在虚拟机，右键单击<span class="uicontrol">“编辑设置”</span>。</span></li><li><span>选择所有除系统盘和占位磁盘外的残留磁盘，单击右侧的<span><img src="zh-cn_image_0000002200055185.png"></span>，执行移除操作。注意不要勾选<span class="uicontrol">“从数据存储删除文件”</span>。</span></li><li><span>单击<span class="uicontrol">“确定”</span>。</span></li></ol>
